It enables you to learn more about astronomy as you use the planetarium-style software. You can view and retrieve information on any of the approximately 20 million objects, including stars, galaxies, nebulae, clusters, the planets and their moons, comets, asteroids, and Earth orbiting spacecraft and satellites, simply by clicking on the object. The appearance of the sky can be simulated from any location on Earth from 100,000 BC to 100,000 AD. You can also even use the software to automatically control an LX-200 or Autostar-based telescope to point to objects of interest.
